Does Kim Jong-un want war or is his hostility just war-mongering rhetoric? The whole world is trying to figure that out. A strategic clue that Kim Jong-un might not want a war may be given by the closure of the Kaesong plant, the industrial plant where South and North Koreans workers worked together in a little capitalist enclave inside North Korea. The plant is financially beneficial to Pyongyang, so closing it down is economically puzzling, although may make strategic sense if the regime wants to send a credible signal of its resoluteness. However, sending South Korean workers home makes no strategic sense if Kim was planning warfare. As, for instance, the Iranian hostage crisis shows, foreign nationals serve better as hostages, so this could be an indication that Kim’s threats are empty rhetoric. Similarly, Pyongyang warned foreign diplomats on North Korean soil that the regime cannot guarantee their safety any more, hardly a good move if foreign nationals serve as bargaining chips as hostages in hot warfare.
